Description

Wärmeaustauschvorrichtung, insbesondere für Speisewasservörwärmer Die Erfindung betrifft eine insbesondere für Speisewasservorwärmer geeignete Wärmeaustauschvorrichtung, bei welcher die das zu heizende Mittel enthaltenden Rohre gruppenweise in vollen Metallkörpern eingebettet sind.Heat exchange device, in particular for feed water preheaters The invention relates to a heat exchange device particularly suitable for feed water preheaters, in which the pipes containing the agent to be heated are in full groups Metal bodies are embedded.

Von den an sich bereits bekannten Wärmeaustauschvorrichtungen dieser Art unterscheidet sich die neue Einrichtung erfindungsgemäß dadurch, daß die vollen Metallkörper parallel zur Richtung der Heizgase ununterbrochen ebene Seitenwände aufweisen und mit- in gleicher Weise durchlaufenden Rippen versehen sind. Durch diese besondere Ausbildung und Anordnung der die Rohre umschließenden Metallkörper und der parallel zur Richtung der Heizgase und der Seitenwandungen der Metallkörper angeordneten durchlaufenden Rippen werden glattwandige geradlinige Durchgangskanäle für die Heizgase gebildet, so daß der Zugverlust des Vorwärmers und dadurch auch der Kraftbedarf der Ventilatoren wesentlich vermindert wird und ein besonders rascher weitgehender Wärmeaustausch- stattfindet. Außerdem wird durch die glatten Wandungen eine- Ablagerung von Flugasche und Staub vermieden, wodurch der Wärmeübergang weiterhin verbessert wird. Eine Reinigung der Durchgangskanäle für die Heizgase braucht nur in wesentlich größeren Zeitabständen als bei den " bisher bekannten Wärmeaustauschvorrichtungen- zu erfolgen bzw. kann bei genügender Geschwindigkeit der Heizgase vollkommen fortfallen, da die glatten, ununterbrochen durchlaufenden Wände. der von den Metallkörpern und deren Rippen gebildeten Durchgangskanäle keine Möglichkeit für das Absetzen von Flugasche bilden und durch die hindurchströmenden Gase selbsttätig gereinigt werden, was insbesondere für Kesselanlagen mit ununterbrochenem Betrieb einen großen Vorteil bietet. Die Zeichnung veranschaulicht die Erfindung an zwei Ausführungsbeispielen.Of the already known heat exchange devices this Art differs the new device according to the invention in that the full Metal body parallel to the direction of the heating gases, uninterrupted flat side walls have and are provided with continuous ribs in the same way. By this particular design and arrangement of the metal bodies surrounding the tubes and that parallel to the direction of the heating gases and the side walls of the metal bodies arranged continuous ribs are smooth-walled straight through channels formed for the heating gases, so that the draft loss of the preheater and thereby also the power requirement of the fans is significantly reduced and a particularly rapid one extensive heat exchange takes place. In addition, the smooth walls A deposit of fly ash and dust is avoided, whereby the heat transfer continues is improved. The passage channels for the heating gases only need to be cleaned in much longer time intervals than with the "previously known heat exchange devices - to take place or can be completely omitted if the speed of the hot gases is sufficient, there the smooth, uninterrupted walls. that of the metal bodies and whose ribs formed through channels no possibility for the settling of Form fly ash and are cleaned automatically by the gases flowing through, which is a great advantage, especially for boiler systems with uninterrupted operation offers. The drawing illustrates the invention using two exemplary embodiments.

Abb. .i zeigt eine Gruppe der das zu heizende Mittel, z. B. Speisewasser, enthaltenden, in volle Metallkörper eingebetteten Rohre im Querschnitt.Fig. .I shows a group of the means to be heated, e.g. B. feed water, containing tubes embedded in full metal bodies in cross section.

Abb. 2 ist eine Seitenansicht zu Abb. i. Abb.3 veranschaulicht in Ansicht eine andere Ausführungsform, bei welcher die Metallkörper schräg zur Richtung der Rohre angeordnet sind.Fig. 2 is a side view of Fig. I. Fig.3 illustrated in View of another embodiment, in which the metal body is oblique to the direction the tubes are arranged.

Die das zu heizende Mittel, z. B. Kesselspeisewasser, enthaltenden Rohre a sind in an sich bekannter Weise gruppenweise in: Metallkörpern ceingebettet, welche gemäß Abb. i zwecks Verminderung des Gewichtes und Materialbedarfs Kanäle j besitzen. Gemäß der Erfindung weisen die Metallkörper c parallel zu der in Abb.2 durch Pfeile angedeuteten Richtung der Heizgase ununterbrochen, ebene Seitenwände und in gleicher Richtung durchlaufende Rippen i auf, so daß glattwandige, dem Durchgang der Heizgase besonders geringen Widerstand bietende Kanäle gebildet werden, durch welche bei raschem und wirksamem Wärmeaustausch der Zugverlust des Vorwärmers und der Kraftbedarf des Saugzugventilators vermindert und Ablagerungen von Flugasche und Staub vermieden werden.The means to be heated, z. B. boiler feed water containing Pipes a are embedded in groups in a manner known per se in: metal bodies c, which channels according to Fig. i for the purpose of reducing weight and material requirements j own. According to the invention, the metal bodies c point parallel to the one in Fig.2 Uninterrupted direction of the heating gases indicated by arrows, flat side walls and ribs i running through in the same direction, so that smooth-walled, the passage channels offering particularly low resistance are formed by the heating gases which with rapid and effective heat exchange, the draft loss of the preheater and the power requirement of the induced draft fan is reduced and fly ash deposits and dust can be avoided.
